 ### 1.2 最大玩家数(-1~31)
 #### `sv_maxplayers <num>`
 - 服务器最多能进多少个玩家(设置为-1则不做修改)
-- **该cvar为采用延迟加载,不能加入到启动项中**
 ### 1.3 禁止大厅匹配
 #### `sv_force_unreserved <0/1>`(置1为禁止)
 - 开启功能会将`sv_allow_lobby_connect_only`的值置0

 ### 1.2 Maximum number of players (-1~31)
 #### `sv_maxplayers <num>`
 - The maximum number of players the server can accommodate (set to -1 for no modification).
-- **This cvar is loaded with delay and cannot be added to the startup options.**
 ### 1.3 Prohibit Lobby Matching
 #### `sv_force_unreserved <0/1>` (set to 1 to disable)
 - Activating this function will set the value of `sv_allow_lobby_connect_only` to 0.
